Why Do Motorcycles Stall?

Does your bike stall out for no reason? Or does it stall when you try to accelerate? Is it difficult to get out of neutral? These can all be signs that your motorcycle is in need of some TLC. Stalling can be the result of anything from an improperly adjusted carburetor to something as simple as a fuel line that is clogged.

So why do motorcycles stall? Many things can cause your motorcycle to stall, and these things can range from improper clutch control up to the gear box to the carburetor. We must be able to recognize the problems at hand, even those that are small and hard to see, in order to properly solve the problem.

Let’s elaborate some of the reasons why motorcycle stall

Problem in the fuel system

A motorcycle stalling out is as frustrating as it sounds. Maybe it’s an annoyance, or an emergency in the case of a sudden loss of power, but either way, you need to figure out what’s causing the problem. It could be anything from a dirty fuel filter to a loose spark plug wire, and a little troubleshooting goes a long way.

  • Clogged fuel filter – Your motorcycle may run normally and ride normally, but when you accelerate, the engine idles higher and has less power. When you accelerate, more fuel needs to pass through the filter to the engine. However, if the fuel filter is filled with dirt and debris, the fuel will not pass properly. This will cause the engine to stall and the vehicle will not accelerate.
  • Clogged fuel injector – Motorcycles need fuel to operate, and the majority of motorcycles use fuel injection systems, which provide fuel to the engine per the systems owner’s manual. These engines need clean fuel to operate, and clogged fuel injectors can cause problems including stalling or sputtering.
  • Incorrect Fuel – a diesel fuel will not work on motorcycle because your bike is a gasoline-type vehicle.
  • Leak in fuel system – if you let the leaks in your fuel system, you will eventually ran out of gas. Not just it will make your bike to stall, it will also cause potential fire from faulty electrical wiring.
  • Low Fuel – Fuel starvation is often the cause of a motorcycle stalling. Fuel starvation occurs when there is not enough fuel in the fuel tank. There are several ways you can ensure there is fuel in your tank. First, it is a good idea to put fresh fuel in your tank regularly. By putting fresh fuel in your tank, you ensure there is enough fuel in your tank to run the engine. Second, check your fuel level before each ride. By checking the fuel level, you can make sure it is at a safe level before you ride. We recommend checking the fuel level before each ride and before fuel starvation occurs.
  • Water in fuel system – Water can get into the air intake system of your car and get into the fuel system, which alters air/fuel ratio and lessens engine power. This situation is known as hydrolock and can cause the engine to stall. The air intake system is composed of the throttle body, induction system and air filtering, all of which can experience water damage. The air filtering system is where the most damage can occur because debris can clog it and rust can build up inside. Water can also enter the air intake system when the engine, radiator or cooling lines get blocked.
  • Too much Fuel in the Carburetor

Exhaust system

If you own a motorcycle, you know there is nothing quite like the sound of it accelerating to life after it’s been sitting in the garage for a while. And there’s no better feeling than cruising down the highway with the wind in your face, feeling free as a bird. However, if you’re concerned about your motorcycle stalling out, take a close look at your exhaust system. The exhaust system helps move exhaust gases away from the engine of your motorcycle, and any blockage can result in a stalling out condition, or even worse, a stall-out crash.

Clogged ignition system

While riding your motorcycle, your engine’s ignition system is an important component of your vehicle, as it controls your car’s engine. Your ignition system is important and needs regular maintenance to keep it running smoothly. If the ignition system stops working, the motorcycle won’t be able to run. Your engine won’t start, and if your motorcycle stalls, you run the risk of an injury or accident.

Cold and wet weather

Motorcycle riders spend a lot of time riding in bad weather, and they know full well that riding in the rain is miserable and unenjoyable. But bad weather isn’t just a hazard to the motorcycle; it can also be a danger to riders.

Bad weather can cause water to go inside air filters resulting water and fuel mixtures.

Dirty and clogged air filter may cause the motorcycle to stall

As air enters the carburetor, it is first filtered through a filter, which helps to remove the dust and dirt in the air before it enters the carburetor. The farther away the air travels from the filter, the cleaner the air is. As the air filter cleans the air entering the carburetor, it will eventually become dirty or clogged and may prevent the proper amount of air from mixing with the fuel, causing your engine to stall.

Out of oil

When the oil in a motorbike gets dirty, it gets thicker and noisier. This causes a blockage, which forces the motorcycle to stall. The cause of this blockage is very likely to be debris and mud.

Wrong gear

The clutch is an important part of a bike’s drivetrain. The clutch is engaged when the engine’s throttle is opened and disengaged when the clutch is wide open. Clutches don’t fail but the cable and clutch plates are (most) often the first part to fail. A “problem” clutch can fail completely to cut out completely.

Another reason is using the wrong gear coming from stop. You might think that you are in the first gear but you are currently in the third gear. This wrong gearing can cause motorcycle to stall.

Rider error

This is the most common reason why bikes stall. Sometimes we are too confident that we forget the basic like properly releasing the clutch, or we forget that our bikes have side stand safety kill switch.

Does stalling a motorcycle damage it

You’ve just purchased your brand-new motorcycle, and it’s time to take it out for a spin. But as you rev it up and take off, you notice something strange: Your engine seems to stall out, even though you’re going 60 mph. This can be frustrating, but there’s no reason to panic. In very rare case, stalling a motorcycle can damage the engine, but most of the time it’s a temporary condition.

Stalling a motorcycle is a safety risk, especially while traveling down a road. The motorcycle may not break the engine, but over several stalls it will slowly wear down, and that can result in damaged components like chain and sprockets.

Can you stall a motorcycle at high speeds

Motorcycle is so designed that it is virtually impossible for engine failure to stall while moving, but it is entirely possible for it to stall when stationary.

Motorcycles are designed to be less susceptible to engine failure when moving, but the rider has to be aware of the bike and how to stop it. Stopping a motorcycle when the engine stalls is more difficult than on a car, as the body is usually positioned at a downward angle while the bike is stopped.
